About Image Brightness & Contrast
Fine-tune your image appearance with real-time brightness, contrast, saturation, and hue controls. Use the live preview to see changes instantly. Reset individual sliders or all at once. Download the adjusted image as JPEG or PNG. All processing runs locally in your browser.
Use Cases
Brightening underexposed phone photos, fixing washed-out or overexposed images, boosting colour saturation for social media, correcting flat-looking product photos, preparing images for print.
How It Works
Applies CSS filter functions (brightness, contrast, saturate) to a canvas via ctx filter, then reads the resulting pixel data. Alternatively uses pixel-level manipulation for browsers without CSS filter canvas support.
FAQs
Is there a reset button?
Yes — reset individual sliders with the × button or click "Reset All" to return all values to defaults.
What is saturation?
Saturation controls the intensity of colours. 0% is fully grayscale, 100% is the original, and values above 100% make colours more vivid.
Will the download maintain original resolution?
Yes. The canvas processes the image at its original pixel dimensions — no scaling occurs.
